Visual C++ - CListCtrl Applying Different Colors for each row

---

We might be using CListCtrl a lot in Visual C++ project. It is often necessary to have the different colors for each row. It is very easy to do it. Look at the following code and how it is used in the sample project.

 

Source Code

// CStudentInformationSystemDlg dialog

class CStudentInformationSystemDlg : public CDialog

{

        .....  

        afx_msg void OnNMCustomdrawList1(NMHDR *pNMHDR, LRESULT       *pResult);

};

 

 

// StudentInformationSystemDlg.cpp : implementation file

//

 

BEGIN_MESSAGE_MAP(CStudentInformationSystemDlg, CDialog)

        ON_NOTIFY(NM_CUSTOMDRAW, IDC_LIST1,         &CStudentInformationSystemDlg::OnNMCustomdrawList1)

END_MESSAGE_MAP()

 

 

 

void CStudentInformationSystemDlg::OnNMCustomdrawList1(NMHDR *pNMHDR, LRESULT *pResult)

{

    NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>( pNMHDR );

 

    *pResult = CDRF_DODEFAULT;

 

    if ( CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage )

    {

        *pResult = CDRF_NOTIFYITEMDRAW;

    }

    else if ( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )

    {

        COLORREF crText = RGB(0,0,0);

        if ((pLVCD->nmcd.dwItemSpec %2) == 0) // even lines

            crText = RGB(255,0,0);

        pLVCD->clrText = crText;

        *pResult = CDRF_DODEFAULT;

    }

}
